COTTON CHOPPER.

, APPLICATION FILED JUNE 16, 1910.

.L 1 9 1 0 1 I nu 0 d e m b a P Inventor Witnesses Attofneys F To all whom it may concern:

lie it known that l, l'iii'i'r (iaitnsox. a citi-i' zen of the United States, residin at Carl-f son, in the county of-Travis an: lotate oi g Texas. have invented a new and useful Cotand consists in the novel caasti' iatii'ai and arrangement of its parts as hereinafter de scribed and shown. u

The ob ect of the invention is to provide a chopper of the character indicated as a simple and durable structure consisting of a wheel supported frame to the axle of.

which is pivotally attached a supplemental frame which in turn is supported at its forward edge portion upon caster wheels. A hoe shaft is carried by the supplemental frame and chopping lipes or a chopping blade may be mounted upon the said shaft, means being provided for raising and lowering the supplemental frame and for guiding. its adjustment and bracing it against lateral strain witlfrelation to tie primarv frame and means also being provided for t irowing the hoe shaft iu.or out of gear with the supportin axle of the main frame. a

In tie accompanying drawings: Figure 1 is a top plan view of the cotton chopper. Fig. 2 is a side elevation of the same. "ig.- 3 is a longitudinal sectional view of the same. Fig. 4 is a transverse sectional view of the same cut on' the line .1-4 of Fig. 1., Fig. 5 is a detail side view of chopping hoes mounted upon the hoe shaft. 1* lg. 6 is a side elevation of a cho iping blade adapted to be mounted upon thelioe shaft.

The cotton chopper'consists of an axle I mounted at its ends upon traction wheels 2 and having a main or primary frame 3 piv-i otally mounted at its rear portions thereon. The frame 3 is made substantially in the form of a yoke. The frame 3 is provided at its forward edge and at a point intcrme-' diate its side edges with a forward pro'cc tion 4 which is mounted upon a truel 6' having ground wheels 6. A lever mocha-i nism 5' is provided for turning and holding. the truck 5 with relation to the frame 3.!- A draft tongue 7 or other draft means is suitably connected with the said truck.

A supplemental frame 8 is pivoted at its" rear portions to the axle 1 between the sidd parts of the frame 3 and the forward poi tion of the supplementalframe 8 is sup-:-

ported by caster wheels 0. The frames 10 of the said caster wheels may be adjusted vertically with relation to the supplemental frame 8 whereby the forward portion: theremam...

:jchisejir distant from the. surface of the ground h-\'t'I--ll is fuleruiiied upon the frame 3 and is irovidedwith an augiilarly with a beveled pinion 17 which mes-hei with in bevel gr'ar wheel 18. mounted upon the intermediate portion of the axle 1. The i'forward end of the shaft 16 is adjustably secured in a sleeve 11) and the rear end of a shaftsection 20 is similarly secured in the forward end of the said sleeve. The forward end of the shaft section 20 is jour- I iialcd in the forward portion of the frame 8. i A nut or stop 21 is mounted upon the for- ;ward end of the shaft section 20 and disposed workiugeud ll'upott which is jouris lo- 1eated normallv against the forward side' 1 of the front edge of the frame 8. A collar .22 is adjustably mounted upon the intermediate portion of the shaft. section 20 and a coil siring .23 is interposed between 'tlie' said col at and the rear surface of the forward edge portion of the frame 8. The

fspring 23 is under tension with a tendency I to hold the shaft sections 16 and .20 together i with the sleeve 19 in rearward position whereby the beveled pinion 17 will be held in most with the beveled gear wheel 18.v

.AIHIS 2t are adjustably mounted in the sleet-0 10 and at their outer ends carrying ehoppmg blades 25.

A lever 26 is fulf erumed upon the cross bar 14 of the frame g S and operatively engages the shaft section 16 so that when the said lever 26 is swung the said shaft 16 inav be moved longitudi- 1 lnally, and through the sleeve 10 the shaft .section 20 is moved against the tension of connected to the crank arm 33, which opersaid crank arm boingadjustably eonncctcd through the adjustable link to the upper end of the pivoted levers 87, I which ates the shaft 3-1 and also its crank arm 35, 1

wfamar fwdraaat s erstwhile.

the coiled spring .23 and thus the beveled a link 30 extending forwardly thereof and i l t operatirelr connecting said shaft with the t s'rrapers 38. ll this niran the. lnanipului 5 lion oi the lever Ill will regulate th uun'e- I uncut. ot" the scrapers 11H toward and from i the ground. As the machine is drawn along a row of plants and the beveled pinion IT is in mesh with the lwrrled gear wheel l8; rotary. morenu-nt. is tram-milled fr m the axle l to the shaft. sections tit and .20 and the sleeve ll). AS the said slrerr rotates upon its axis the hue blades 25 are carried around and chop out thmexressive plants in the row. However should the rliopplng Mad! 2!) he applied to them-ha it aeetions 16 and .20 the cxreawive plants will he. removed from I. the row in a similar manner. inasmuch as I l the forward portion of the arm 28 is located hetween the guides 27 and may more vertically the frame 8 is braced against lateral movement during the plant chopping l operation.

llaving descrihed the invention what 1 claim as new and desire to secure by Letters Patent is: I A cotton chopper comn-ising a wheel r mounted axle, a primary 'rame pivoted at I I its rear end upon the axle and having at: v g the intermediate part of its forward edge a 9 forwardly projectingportioinawheelmounted truck supporting the forwardly u'o- I jecting -portion of said frame, a secondary framea so pivoted upon the axle and lying! f within the first said fran'ie, a shaft ournaled-upon the secondarv frame, means;

axle, hoe lilades carried by the shaft, rerti-- eally disposed parallel guides depending ffrom the forwardly pro ecting portion of t the primary frame, an arm mounted upon the secondary frame and received between t I the guides for free vertical lay, and a supt porting caster wheel attaeied to the forward portion of the secondary frame.

In testimonv that I claim the foregoing as my own, I have hereto atlixed my signa-' ture in the presence of two witnemcs.
